Bleeding brakes...

This is driving me crazy... Im trying to do the "simple" thing - bleed my brakes on my -93 155 q4 with ABS. The system had been empty for a couple of years.
I have tried to vacuum suck the fluid, from the caliper, and it doesent work. Now I have the system under presure from the brakefluidreservoar. Nope. Not a single dropp of fluid is going anywere... The clutchsystem was simple to bleed this way. The brakepedal is moving, Ive tried to bleed this way to... It sims that the system is blockt some how. The workmanual isnt much help...
:C

Have you tried it with the ignition on?

Or engine running.

You say pressure from the reservoir, is the cap sealing ok, what pressure are you using?

With the ignition on yes, but not with the engine started. It isnt reedy yet...
Seal ok, up to 2 bar...

As far as I can remember, you need to have the sitting on its wheels.....

Why? In front i shouldent matter, or...? In the back the loadvalve is adjusted so it thinks its on wheels.
